Alpha Ortho k fitting requirement
A careful assessment will be carried out during fitting.
Experience regarding wearing glasses, contact lens usage, cases of eye diseases and systemic diseases will be asked by the optometrist. The condition of the eyelids, eyelashes, cornea, and conjunctiva has to check to confirm whether the patient is suitable to wear “α ORTHO®-K“.
2.Corneal shape refractive examination
Refractive examination and subjective refraction based on the eye chart and refractive lens insert will be conducted. After that, the optometrist will analyze the shape of the cornea and calculate the corneal radius of curvature according to the keratometer and corneal topography.
Follow regular follow-up visit schedule for inspections. After 1 week of wearing the lens or later in future during the inspection, the fluorescein staining will be applied when necessary . If the lens is misaligned, or vision desired after correction is not obtained, the patient will have to come and recheck again in 1 or 2 weeks. If there is no problem in the inspection, the follow up schedule is 1 month, 3 months and regular follow-up visits every 3 months.
Lastly, in order to keep the lens clean, the lens casing must be replaced regularly. It has been reported many eye infections happened due to dirty lens casing.

Di bawah adalah 6 langkah penting penanggalan kanta lekap.
1. Sebelum mengeluarkan kanta lekap, sangat digalakkan mencuci tangan dengan sabun dan air dengan teliti. Ini untuk mengurangkan kemungkinan jangkitan mata. Kumpulan oftalmologi mengesyorkan agar tidak menggunakan sabun yang mengandungi minyak atau wangian tambahan, kerana sabun boleh melekat pada permukaan lensa.
2. Balikkan bekas simpanan anda dan goncangkan larutan kanta lekap yang tersisa, kemudian biarkan ia kering secara biasa atau keringkan bekas dengan kain bersih dan segar. Ini adalah penting dalam langkah penanggalan kanta lekap kerana kotoran boleh melekat di dalam bekas sekiranya tidak dibasuh dengan bersih.
3. Semasa pembuangan kanta lekap, berdiri di depan cermin.
4. Lihat ke atas. Dengan menggunakan tangan yang tidak dominan, angkat kelopak mata atas dari mata anda dengan jari telunjuk. Dengan tangan yang dominan, tarik kelopak mata bawah ke bawah dengan jari tengah.
5. Untuk melepaskan kanta lekap, cubit perlahan lensa dengan pad jari telunjuk dan ibu jari anda. Cuba jangan menarik lensa terlalu keras sehingga tidak melipat.
6. Setelah menanggalkan lensa, letakkan lensa di telapak tangan yang lain dan masukkan larutan lensa serbaguna segar ke permukaan lensa. Jika menggunakan kanta lekap yang dimaksudkan untuk dipakai selama beberapa hari sebelum penggantian, pastikan memasukkannya ke dalam casing yang memiliki “L” ke kiri dan “R” untuk kanan yang ditandai dengan jelas, sehingga tidak bercampur. Ingatlah untuk selalu mengikuti arahan yang disertakan bersama penyelesaian pembersihan dan pembasmian kuman anda.
Berapa lama kanta lekap bertahan?
Kanta lekap sekali pakai biasanya berlangsung antara satu hari hingga satu bulan, sementara lensa keras seperti RGP dan PMMA boleh bertahan hingga satu tahun atau lebih lama.
Mengapa kadangkala sukar untuk menanggalkan kanta lekap?
Hal ini boleh berlaku jika memakai kanta lekap selama berjam-jam atau kerana mata kering. Untuk mengeluarkannya, cuba titiskan sedikit larutan pada jari dan kemudian sentuh permukaan kanta lekap agar mudah dikeluarkan. Selain itu, anda boleh titiskan air mata palsu ke mata. Ia boleh didapati di farmasi.
Apa yang akan berlaku sekiranya menangis semasa memakai kanta lekap?
Tiada masalah sekiranya anda menangis semasa memakai kanta lekap. Walau bagaimanapun, lensa mungkin tidak melekat pada mata dengan baik kerana air mata. Jangan menggosok mata sambil menangis kerana ia boleh merosakkan kanta lekap atau menyebabkan kanta anda koyak.
Bolehkah kanta lekap hilang di mata?
Tidak. Ia adalah mustahil sekiranya kanta akan terperangkap di belakang mata atau sepenuhnya hilang dalam mata.
Apa yang berlaku jika tidak pernah mengeluarkan kanta lekap?
Apabila kanta lekap tidak dikeluarkan, maka, terjadilah sesuatu yang disebut “neovaskularisasi kornea” kerana kekurangan oksigen ke mata. Saluran darah di mata akan tumbuh secara tidak normal dan akan disarankan oleh pakar optometri untuk berhenti memakai sebarang kanta lekap.
1. Before contact lens removal, it is highly recommended to thoroughly wash your hands with soap and water . This is to reduce the chance of an eye infection. The ophthalmology group recommends not to use any soaps that contains extra oils or fragrances, as soap can stick to the surface of a lens.
2.Flip over your storage case and shake out any leftover contact-lens solution, then air dry it or dry the case with a fresh, clean cloth.
3. During contact lens removal, stand in front a mirror.
4. Look upward. Using non-dominant hand, raise your upper eyelid away from your eye with your index finger.With the dominant hand, pull lower eyelid down with middle finger.
5. To remove contact lens gently pinch the lens with the pads of your index finger and thumb. Try not squeeze the lens too hard so that it does not fold.
6. After removed the lens, place the lens in the palm of another hand and squeeze fresh multipurpose lens solution onto the surface of the lens. If using contact lenses that are intended to be worn for multiple days before replacement, make sure to put them in a case that has “L” for left and “R” for right clearly marked, so that wont mix up. Remember to always follow the instructions that came with your cleaning and disinfecting solution.
How long does contact lens last?
Disposable contact lenses generally last between one day to one month, while hard lenses such as RGP and PMMA can last up to one year or longer.
Why is it sometimes it is so hard to remove contact lens?
This can happen if wearing the contact lens for long hour or due to dryness of the eye. To remove it, try to apply some solution on the fingers and then touch the surface of the contact lenses for easy removal.
What will happen if cry while wearing the contact lens?
It is safe to cry while wearing thecontacts. However,the lens may not adhere to the eyes very well due to tears. Do remember not to rub the eyes while crying because rubbing might damage the lens or cause the contacts to drop out.
Can contact lens get lost in eye?
No. It is impossible that the lens will get trapped behind the eye or completely lost in the eye.
What happens if never take out contact lens?
When contact lens is not removed, the eye can develop something called “Corneal neovascularization” that occurs because of the lack of oxygen to the eye. The blood vessels in the eye will grow a lot that the optometrist will advise to stop wearing any contact lens.
Rigid Gas Permeable (RGP) lenses have been in market since 1960’s. The latest RGP contact lenses has the best advantages as it allows more oxygen to pass through our eye. They are often referred to as oxygen permeable lenses and are available in daily wear and extended wear options.
We are going to introduce top 5 contact lens solution recommended by our optometrist. It is important to take good care of your contact lenses in order to extend the life of your contact lenses, and protect the safety and health of your eyes. Lens care varies depending on material and wearing schedule. Daily disposable lenses are discarded after a single use and thus require no cleaning. Other lenses require regular cleaning and disinfecting to prevent surface coating and infections.
There are many ways to clean and care for contact lenses, typically called care systems or lens solutions. Two types of solution that are commonly used included:
Multipurpose solutions
Multipurpose solutions are the most common method for rinsing, disinfecting, cleaning, and storing soft lenses. Clean your lenses, then rinse and disinfect, all with the same solution. When you are ready to wear the lenses, rinse them again.
Hydrogen Peroxide solutions
Hydrogen peroxide can be used to disinfect contact lenses. Care should be taken not to get hydrogen peroxide in the eye because it is very painful and irritating. With “two-step” products, the hydrogen peroxide must be rinsed away with saline before the lenses may be worn. “One-step” systems allow the hydrogen peroxide to react completely, becoming pure water. Thus “one-step” hydogen peroxide systems do not require the lenses to be rinsed prior to insertion, provided the solution has been given enough time to react.
Being concerned with your eye health and contact lens care, Avizor, the expert in solutions, has a single solution for every problem and occasion. Avizor is a laboratory in Madrid, Spain dedicated to the manufacturing of solutions for the cleaning and maintenance of all types of contact lenses. Avizor have been working in this field since 1985. Over the years, Avizor considered to be one of the best contact lens solution brand available.
As for multipurpose solution, there are two different types of solution to suit for different types of contact lens wearer. This include the following:
1) Avizor Unica Sensitive: “In a class of its own”
For users with sensitive eyes: With the addition of extraordinary lubricant agent (Sodium Hyaluronate or Hyaluronic acid), the solution has the following effects:
Protect cornea thanks to the prolonged time in the eye
Improved tear film stability- Hyaluronic acid is one of the most moisture-absorbent molecules in nature.
Increases the hours of comfortable use- Hyaluronic acid easily spread over the eye during blinking.
Accelerates healing time preventing irritation and redness caused by the mechanic action of the lens.
Clarify your vision by reducing the ocular symptoms of dry eye.
2) Avizor Alvera with Aloe Vera: “Protects in the most natural way”
especially designed and tested for use with silicone hydrogel lenses.
The use of contact lenses can alter the physiology of the ocular tissue and may create intercellular spaces allowing the entry of foreign substances.
Aloe Vera creates a film over the epithelium that prevents the entry of these substances that may damage the epithelium, thus reducing the risk of irritation.
removes lipids more effectively, but also reduces the affinity of lipids to adhere to the surface of the contact lenses, which considerably increases hygiene and comfort in the use of silicone hydrogel lenses.
3) On the other hand, Hydrogen Peroxide solution produced by Avizor is called Ever Clean.
It is a revolutionary “One-step” system for the cleaning and disinfection of all types of contact lenses (Soft contact lenses and Rigid Gas Permeable lenses). Ever Clean contact lens solution is the result of eight years of research into creating a product to clean all contact lenses throughly without the need for rubbing in only 2 hours.
How it works?
Thanks to its 2 layer table EVER CLEAN has double action:
The white layer performs the cleaning action from the first movement, while eliminating lipids and proteins from the surface of the lens.
The green layer acts slowly and extensively controlling the disinfection and neutralization of the hydrogen peroxide.
On the whole, the Ever Clean tablet performs a powerful disinfecting and cleaning action after which the peroxide is transformed into a preservative-free saline solution where the lenses are stored and ready to use.
Ever Clean is specially recommended for users with:
1. Problems of deposit accumulation
No more deposit due to a greater capacity of cleaning and disinfecting.
2. Problems with allergies
After neutralization the final solution contains no preservatives.
3. Problems manipulating the contact lenses
As you no longer have to rub, users are less likely to damage or tear their lenses.
Enhances comfortable wear and reconditions the lens surface to retain moisture.
Removes protein daily
Sterile silicone hydrogel and soft contact lens
5) Opti-Free Pure Moist ” All day comfort”
Multipurpose solution
Provides comfort and moisture from insertion to removal
Removes protein deposits
Reduces lipid deposition
Sterile silicone hydrogel and soft contact lens

Our professional optometrist can advise you to choose different contact lens care solutions that can suit different individuals.
Menicon Ortho-K Lenses works as a continuous wear lenses to correct myopia. Myope is an eye condition of where distance image appear blur and near image look clear. Normally, the standard correction available for myopia correction is using glasses, contact lens or lasik surgery. Today, there is another great alternative way to correct myopia condition, named as orthokeratology.
Orthokeratology, also known as Ortho-K is a non-surgical procedure of reshaping the cornea gently while you sleep, with a specially designed therapeutic gas permeable contact lens. This type of contact lenses can have a successful fitting by correcting the refractive error, primarily myopia (near-sighted) but astigmatism and hyperopia (long-sighted). Ortho-K sometimes called corneal reshaping (CR), corneal refractive therapy or even vision shaping.
Ortho-K lenses gradually change the cornea curvature overnight to reduce corneal refractive power, resulting in images being focused on the retina. The successful of Ortho-k fitting occurs as vision will be improved after remove the lenses without the needs of wearing any glasses or contact lenses during the day.
Process of cornea reshaping in overnight
The main objective of Ortho-K is help to slow down myopia progression in children. The myopia epidemic in Asia is evident because the prevalence of high myopia among young adults is higher among Asian (6.8% – 21.6%) compared to non-Asian populations (2.0% – 2.3%). [YL Wong et al 2016]
Besides that, Ortho- K lenses is a non-surgical and reversible vision correction treatment. For those children who wish spectacle free during day time activities but too young for LASIK, Ortho-K is the most suitable option. Ortho-K is a specially designed gas permeable contact lens which offers high oxygen transmission to maintain eye health.
Jennifer (2018) stated that when Ortho-K used for partial or full correction of myopia, has been shown to slow down myopic progression in children by 35-56 % as compared to controlled group who wearing spectacle or contact lenses.
Example of successful Ortho-K fitting
The criteria for Ortho-K including myopia below -6.00D and astigmatism below -2.00D. Children and teenagers with myopia progression (power increment) are suitable for Ortho-K treatment. Individuals who are active in sport, individual whose occupation do not encourage eyewear. Ortho-K is another best alternative to LASIK. Compliance and independent characteristics is very important as well.
Ortho-K is a specially designed gas permeable contact lens that wears overnight to reshape the corneal curvature and correct the refractive error which provide a spectacle free clear vision to carry on dailies activities. For more information, do contact your best optometrist in KL
Komplikasi kanta lekap kerap berlaku sekiranya langkah pemakaian dan penjagaan tidak dipatuhi. Kanta lekap memberikan faedah penglihatan. Sekiranya anda pemakai kanta lekap, kanta lekap anda harus merasa selesa dan membolehkan anda melihat dengan baik. Terdapat banyak komplikasi kanta lekap yang mungkin dialami oleh pemakai kanta lekap iaitu komplikasi yang disebabkan secara langsung atau tidak. Mekanisma di mana lensa sentuhan mendorong perubahan adalah: trauma, penurunan oksigenasi kornea, penurunan kelembapan kornea dan konjungtiva, rangsangan tindak balas alergi dan keradangan, dan jangkitan.
Gejala Sakit:
Sakit pada mata- Semua pesakit kronik yang menggunakan kanta lekap mungkin mengalami pengurangan deria sentuhan dan kurang sensitif kepada bahan asing.
Penurunan ketajaman visual: ketidakteraturan permukaan hadapan kornea.
Hiperemia konjungtiva
Intoleransi kanta lekap
Komplikasi Kanta lekap Utama
Edema kornea – disebabkan oleh keadaan kornea kekurangan oksigen sama ada ianya kronik atau tidak, bahan kanta lekap, dan kanta lekap yang tidak dipasang dengan betul. Untuk merawat keadaan ini, seseorang harus memilih bahan lensa dengan tinggi kebolehtelapan oksigen (oxygen permeability), mengurangkan masa memakai kanta lekap, dan memastikan kanta lekap itu optimum untuk dipakai.
Kornea yang tidak serata (corneal distortion) – Perubahan kelengkungan kornea yang disebabkan oleh pemakaian kanta lekap. Rawatan merangkumi memastikan tidak ada astigmatisme yang tidak teratur, pemasangan lensa sentuh, dan perubahan pada bahan lensa.
Neovaskularisasi – Ia terjadi sebagai tindak balas kepada faktor yang sama yang menyebabkan neovaskularisasi pada bukan pemakai kanta lekap, termasuk hipoksia kornea dan keradangan. Rawatan yang boleh dilakukan ialah berhenti memakai kanta lekap, dan suntikan kortikosteroid topikal untuk membantu mengurangkan salur darah membentuk.
Konjungtivitis Giant Papillary– lebam yang muncul di bawah kelopak mata. Pemakaian kanta lekap tidak dibenarkan sehingga lebam tidak larut. Untuk mengecilkan lebam, sila lakukan kompresasi sejuk menggunakan tuala bersih dan ais, tekapkan ke mata selama 1 minit dan lakukan berulang kali.
Sekiranya anda mengalami masalah di atas. Sila dapatkan rawatan dengan segera atau buat temu janji dengan kami.
With all that is positive about Ortho-K and their high percentage rates of slowing down the rate of increase Myopia (Nearsightedness), there are side effects that you have to look out for.
